Capillary flowmeterIt is a gas flow measurement device designed based on the principles of fluid mechanics, whose core is to reflect flow changes through the pressure difference generated when gas flows through a capillary tube.

　　Capillary flowmeterSelection and usage suggestions:

Selection Principles

Fluid characteristics: Consider parameters such as temperature, pressure, density, viscosity, etc. of the gas to ensure that the selected capillary flowmeter is suitable for the properties of the measured fluid.

Measurement range: Select the appropriate flow measurement range according to actual needs to avoid inaccurate measurements caused by exceeding the range.

Accuracy requirements: Select the appropriate capillary flowmeter model based on the accuracy requirements of the experiment or industrial process.

Economic factors: Taking into account factors such as instrument purchase costs, installation costs, and operating costs, choose products with high cost-effectiveness.

Precautions for use

Keep clean and dry: When using, keep the capillary flowmeter clean and dry to avoid impurities affecting measurement accuracy.

Select appropriate indicator medium: Choose a liquid that is immiscible and non reactive with the gas according to its properties as the indicator medium.

Regular calibration: Regularly calibrate the capillary flowmeter to ensure that the measurement accuracy meets the requirements. The calibration method can use soap foam rising method, etc.
